About Fuses

Ferrule Style

Knife-Blade Style

With a quicker response than standard fast-acting fuses, these fuses provide the best protection for sensitive electronics.

Breakthrough current, labeled on the fuse as IR, is the maximum current that a fuse can safely stop in the event of a short circuit.
